This invention relates to wheels, designed for use on vehicles of various kinds for travel on land, or tor use on the water, and

" one of the principal objects of the invention is to provide alight, but strong and durable wheel fo'r use on vehicles for both land and water, provided with air compartments to renderthe wheels buoyant, and to provide means for connecting a tire to the tread portion of the wheel. p

Another "object of the invention is to provide a buoyant wheel for auto vehicles, said wheel having a number of propeller vanes or blades connected thereto for propelling the vehicle over the Water.

These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation and sectional fiiew of an axle broken. away in the center a d showing the. wheel connected thereto;

adein accordance with this invention, and

V. Fig. 2 is an end view of one of the wheels.

Referring to the drawings, the numeral 1 designates. an axle which is preferably square in cross section. The wheel is formed by means of a wooden or metal disk 2 having a central squared aperture through which Copies of this patent may be obtained for five cents each, by addressing the Commissioner or Patents,

tending through the disk 2 and forming the inner wall of the air chamber 4 aretubular axle bearing portions which are preferably rectangular in cross section so-that the axle will fit closely therein.

Secured to the outer orv opposite sides of each of the disks 2 is a buoyant air container 11, made in all essential particulars like the container 3, but provided however, upon its outer surface with a plurality of propeller vanes 12. This buoyant container is also secured to the disk 2 by means of a ring 7" through'which the bolts 8 pass to assist in holding the container in place on the disk. The annular rings 7 and 7 a are spaced apart and secured between them is a rubber tire 13 of any suitable form or construction.

From the foregoing itwill be obvious that a wheel made in accordance with this invention may be used on a vehicle for traveling on land or for propelling the vehicle over the water, and that the construction is strong and durable, and that the device will operate" eiliciently under the various conditions met.

with.

What is claimed is l. A buoyant wheel comprising a (118k,

frustoj-conical air tight containers on opposite siues .of said disk, propeller vanes on one of sa'id containers, rings for securing-the.

containers in place on opposite sides of the disk and a tire secured between said rings.

2. A buovant propeller wheel for auto vehicles comprising a rectangular. tubular bearing through which the axle is designed to extend, a disk mounted on said axle, frusto-conical air containing elements, se-

cured one at each side of said disk, said coni tainers having propeller vanes connected thereto, rings secured on opposite sides of said disk for holding the air containers 111 place, and a tire disposed between said rings. In testimony whereof I afiix my signature in presence of twoKvitnesses.
